I do not understand the significance of the compressor specs, but when I started using the Aero Eclipse XL nebulizer, which I like, I read in the instructions that it should be used with a compressor with a given flow and operating pressure. Since the compressor I had from Lincare did not meet those guidelines, I bought an Ombra compressosr, made by the same company as the Aero Eclipse XL (and also the Aerobika). The Aero Eclipse XL nebulizer can also be attached to the Aerobika and used together. Donna
